Summary of the invention

In view of this, this utility model aims to provide a kind of simple in construction, reasonable in design, fixation, On the premise of ensureing ankle joint degree of freedom, its comfort level is high, and safety is high, nature of taking action, and is suitable for The ankle joint of walking on various road surfaces.

For reaching above-mentioned purpose, the technical solution of the utility model is achieved in that a kind of ankle joint, Including a base plate and a twisted plate, one end of described base plate is tangent with the outer wall of twisted plate, described twisted plate It is positioned at the top of base plate, between described twisted plate and base plate, is provided with a support column, the inside of described twisted plate Being flexibly connected a joint handle on bottom surface, the top of described twisted plate is provided with a limited mouth, and described joint handle is worn Go out limited mouth.

Further, the inner bottom surface of described twisted plate is provided with a bearing, solid on the inner ring of described bearing Fixed one fixes post, and described joint handle is movably connected on the top of fixing post.

Further, the top of described fixing post is provided with a cell body, and the bottom of described joint handle is flexibly connected In cell body.

Further, the inward flange of described limited mouth is provided with cushion rubber.

Further, described twisted plate is ellipsoidal structure.

Further, described support column be provided around reinforcement.

Further, the both sides of described base plate are provided with limiting plate, and the limiting plate of both sides forms environmental protection shape structure.

Further, described base plate is provided with fixing hole.

Further, the material of described base plate and twisted plate is CoCrMo alloy.

Further, the material of described joint handle is Ti-6Al-4V.

Relative to prior art, this utility model has the advantage that

This utility model simple in construction, reasonable in design, fixation, before ensureing ankle joint degree of freedom Putting, its comfort level is high, and safety is high, nature of taking action, and is suitable on various road surfaces walking.
